# Approaching the capped amount

**Subscription approaching capped limit** (`subscription.approaching_capped_amount`) fires when a store on usage-based pricing is nearing the cap it agreed to. Past the cap, Meridian can't charge for further usage, so this is the moment to ask the merchant to raise it.

## When it fires

From Shopify's `app_subscriptions/approaching_capped_amount` webhook. Shopify decides when a subscription counts as "approaching"; the cap itself is the **capped amount** you set on the plan's [usage event](/introduction-6) terms.

The webhook also refreshes the recorded subscription state, so a plan or status change carried alongside it lands in the store's record too.

## What it carries

The store's [variables](/automation-variables), plus `subscription_plan` and `subscription_status` from the subscription payload.

## Building on it

* Email the merchant that usage is approaching the cap, with what happens if it's reached. This is the one automation that directly protects usage revenue.
* Branch on `subscription_plan` to word it differently per tier.
* Notify your own team as well, by adding a second send addressed to [specific people](/send-email).

<Note>
  This trigger is about the **merchant's** cap on your usage charges, not about your Meridian allowances. For your own plan limits, see [Billing and usage](/billing).
